  • Standard deviations of estimates are shown in parentheses; number of runs (out of a total of 30) for which minimum or maximum support limits appear to occur at a boundary of 0 or ∞, or ML estimates that occur at ∞ are shown in brackets. Runs for which the ML estimate → ∞ were not included in the means.
